WINIDING DRUM.

Application :filed September 20, 192631. Serial No. 411,454.

To all whom it may concer/r1.:

Be it known that I, NOAH S. HARTER, a citizen of the United States, residing at Waukegan, in the county of Lake and State of Illinois, have invented certain new and useful Improvements in 1Winding Drums, of which the following is a specification.

This invention relates to winding drums.

lt is particularly useful for winding long strips of material into rolls. V

Many varieties of goods such for example as wire fencing, sheet rooting, print paper, etc., are marketed. in rolls. The rolls ordinarily must loe tightly wound and considerable diiliculty is experienced in removing the drum or core from the center of the roll after the same has beenl wound.

An object ofthe present invention is to provide a drinn. upon which thestri'p material may be readily wound and. which can` 'be easily and quickly removed from the center of the roll.

Other objects will hereinafter appear.

An embodiment of the invention is illustrated in the accompanying drawing.

The views in the drawings are as follows:

,F ig. 1 is a longitudinal cross section of a drum and its supporting and driving members.

liig. 2 is an end elevation thereof.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a section on the line le- 1l of Fig. 1, and

Fig. 5 is a section on the line 5--5 of Fig. 1.

The drum, when in winding position, is supported on a pair of pedestals or supports 7 land 8 which may be a part of the machine making the fence, roofing, etc., or

' may be mounted separately thereof.

The winding surface of the drum is composed of two substantially semi-cylindrical sections, a. fined section 9 and a movable section 10. Section '9 is rigidly secured to a shaft 11, being supported thereon near op @site ends by means of wehbed spokes 12. IShaft 11 is of rectangular cross section throughout the greater portion of its length and the'hubs of spokes 12 have rectangular holes therethrough, in which the shaft fits. Spokes 12 may be secured to shaft 11 by suitable means such as pins 13.

The opposite ends of shaft ,11. are provided with cylindrical projections 14 and 15. Projection 14 is adapted to fit into a c lindrical socket 16 in the end of a shaft 7. Shaft 17 is journaled in a bearing on pedestal 7 and has a driving pulley 18 keyed thereto.

Projection 15 is adapted to fit into a cylindrical socket in a shaft 19 slida'bly but non- 1 "i rotatably tal 8. v

Shaft 17 has a collar 20 rigidly secured journaled in a bearing on pedesthereto. Collar 20 is providedwith a number .of notches or depressions 21 in its circumferential surface.

Drum section 10 has a spoke 22 secured to its inner surface near one end and a spoke 23 secured to its inner surface near the opposite end. Spoke 22 is provided with a radially. elongated slot 24 through which passes shaft 11. The bottom of this slot limits the outward movement of section 10,.. y

so that when the section is in its extreme outward or normal winding position, the

outer surface of the complete drum is su'by This position is- Spoke 23 is similarly slotted to allow in" ward and outward movement of end of section 10.

When in expanded or winding position on the machine, section 10 is held in an outward position at one end by a lug or pin 25. Pin 25 isthreaded into spoke 22|and is adapted to rest in one of the notches 21 in collar thev opposite 20. When so seated, the pin retains this end of the drum section 10 in its outward position and also serves to drive the drum.

The opposite end of section 10 is held in its outward or drum expanding position by a bearing block 26, which is rigidly secured to the inner side of section 10, and, when the drum is in winding position, is seated on the end of shaft 19.

Shaft 19 may be longitudinally 'reciprocated in its bearing by a lever 27; Lever 27 lies in a. slot in the end of shaft 19 and is pivotally secured thereto by a pin 28. Lever 27 is pivoted to a link 29 which is pivoted to the frame or pedestal 8.

.Lever l? has a latch- 30 pvotally connected thereto. Latch 30 is provided with a slot 31 in its lower side. Slot 31 has a depression 32 at one end. The slot and depression in latch 30 co-operate with a lug 33 projecting from pedestal 8 to retain the latch in winding position. A pin il prevents latch 30 from being raised too high.

The operation of the drum is as follows:

During the winding of the roll the drum is in the position and condition shown by the full lines of Fig. 1. The fencing or other strip of material is wound thereon as it comes from the machine.

Tight windingrr may be obtained in various ways. For example the driving belt or pulley 18 may tend to drive the drum faster than the strip is fed from the machine. The belt will consequently slip but the tendency to drive the drum faster than required will wind the strip tightlythereon.

When a complete roll is wound, the machine is stopped and the end of the roll fsecured by tying or otherwise fastening the same. rThen latch 30 is raised and lever 27 is pulled outwardly to the dotted line position. This movement of lever 27 withdraws shaft 19 removing the support for one end of the drum. The drum and the roll thereon drops to the floor or a platform.

Both ends of section 10 have lost the support which keeps this section in its outward or expanding position and the slotted spokes allow the section to move inwardly. This movement contracts the drum so that it may be easily removed from the center of the roll.

To replace the drum it is simply lifted by the movable section which allows shaft 11 to drop to thev bottom of the slots in spokes 22 and 23. Projection 14 is inserted in socket 1G with pin 25 lying in one of the depressions in collar 20. Lever 27 is moved inwardly so that projection 15 of shaft 11 is inserted in the socket in shaft 19 and is The for the Winding locked in this position by latch 30. drum is then in condition of a new roll thereon.

In replacing the coil winding drum on its supports, the end 1.4L is first inserted in the opening 16 while the drum is downwardly inclined therefrom7 then disk 2O is rotated until one of the notches 21 is above the axial support 1l, whereupon the lower end is then raised by contact with section 107 whereupon pin 25 will enter notch 21 and the shaft 19 inserted within the drum, as shown after the drum has been raised to horizontal position.

Having described my invention what l claim as new and desire to secure by Letters Patent is:-

1. A winding` drum comprising 'two separated segrments; an angular shaft secured to one segment; an axially movable segment having brackets with'relatively enlarged radially extending openings within which the angular shaft is contained; a rotatable drivingr disk at one end having an axial perforation to receive one end of said shaft and a notch in its periphery to receive a pin eX- f tending;y intothc notch from said bracket; a pin secured to the bracket to hold the segments in concentriespaced relation when in the` notch and a vsupport at the other end of the drum to hold the segments spaced apart.

2. A winding drum comprising a shaft, a cylinder section fixed to the shaft. a cylinder section having ay slotted connection with the shaft and movable thereon to approach and recede from the fixed section to contract and expand the cylinder7 a separable drivingv connection at one end of the cylinder for driving the same and supporting one end of the shaft and the movable section in eX- panding position, a separable support for journaling` the opposite end of the shaft and holding` the opposite end of the movable section in expanding position, and means for withdrawing the separable support to release the shaft and the movable section.

n ln testimony whereof l hereunto Subscribed my name.

NOAH S. HARTER.
